Frequently Asked Questions

What's the difference between Predose and Fresh mode?

Predose pre-grinds 1–2 doses into a holding chamber for rapid dispensing during rushes; Fresh grinds on demand per shot, giving more control when things are quieter.

How long do the burrs last?

Roughly 1,200kg of throughput before performance drops; the touchscreen will alert you when it's time to swap them.

Does it need Wi-Fi to work?

No. Wi-Fi is optional and only needed if you want remote monitoring or connected features. Core grinding functions work standalone.

How fast can it grind a dose?

About 1.6 seconds for a 7g espresso dose, making it suited to high-volume service.

Is cleaning and burr replacement difficult?

No, the Lock & Load system opens the grinding chamber quickly without losing your calibrated grind settings.
